The Cell Cycle

G1 phase

S phase

G2 phase

Stages of Interphase

• G1 phase – Gap 1 – cells grow• S phase – Replication of DNA• G2 phase – Gap 2 – cells prepare to divide

(creation of organelles and molecules needed for a new cell)

Cleavage furrow

• The area of the cell membranethat pinches in to separate thedividing cell into 2 new cells.

• Can be seen in Telophaseand Cytokinesis

Cell plate

• the divider that forms in a plant cell during cytokinesis

Cell plate forming

Homologous chromosomes

• Chromosomes that are the samesize, same shape, and carry genes for the same traits

Carcinogen

• Substance that causes cancer
